Microchip Technology TEMLP001

Overview

TEMLP001 from Embed is a USB-powered in-circuit programmer designed exclusively for 3.3V PIC® microcontrollers, including PIC24H, PIC24F, dsPIC33F, and PIC18FJ families. It delivers up to 100mA Vdd current, enforces strict 3.3V signal limits to prevent overvoltage damage, and features labeled programming pads plus an extra ground pad for low-crosstalk, multi-meter cable routing.

For engineers reviewing the TEMLP001 datasheet, TEMLP001 pinout, TEMLP001 application, or TEMLP001 equivalent, key selection criteria include 3.3V-only target compatibility, USB bus power dependency, absence of included cables, scriptable runtime software support, and host library API availability for custom memory read/write/verify integration.

Technical Context

The TEMLP001 operates as a host-controlled programming interface with no onboard voltage regulation beyond USB 5V-to-3.3V level translation. All programming signals (PGC, PGD, Vpp, Vdd, GND) are routed to exposed, labeled surface-mount pads-not headers-requiring custom cabling.

It supports ICSP™ (In-Circuit Serial Programming) protocol timing compliant with Microchip's 3.3V PIC MCU specification, but excludes high-voltage programming modes (e.g., LVP disable, 12V Vpp), making it incompatible with 5V-tolerant or legacy PIC devices.

FAQ

Does the TEMLP001 support 5V PIC microcontrollers?

No. The TEMLP001 is strictly limited to 3.3V PIC MCUs-including PIC24H, PIC24F, dsPIC33F, and PIC18FJ families-and cannot generate or tolerate voltages above 3.3V on any signal line. Using it with 5V PIC devices risks permanent damage due to missing high-voltage programming capability and lack of Vpp boosting circuitry. Always verify target voltage rating before connecting the TEMLP001.

What cables or connectors are required to use the TEMLP001?

The TEMLP001 provides no pre-assembled cables. Users must fabricate custom cables using its labeled SMT pads (PGC, PGD, Vpp, Vdd, GND, plus an extra GND). The extra ground pad reduces crosstalk and supports stable operation over cable lengths up to several meters. USB-A to micro-B cable is needed for host connection but is not included with the TEMLP001.

Can the TEMLP001 be used for production programming of PIC MCUs?

Yes-the TEMLP001 supports scriptable runtime execution and includes a documented C/C++ host library API, enabling integration into automated test fixtures and production lines. Its 100mA Vdd output powers small targets directly, and its ICSP™ compliance ensures reliable programming across supported 3.3V PIC families. However, throughput is lower than high-speed gang programmers, making it best suited for low-to-mid volume production or engineering validation.

Is the TEMLP001 compatible with MPLAB® X IDE?

No native integration exists-the TEMLP001 does not appear as a debugger/programmer option in MPLAB® X IDE. It requires Embed's standalone software or user-developed applications built on the provided host library API. While functional for programming, it lacks real-time debugging capability and cannot replace MPLAB ICD or PICkit tools within the MPLAB X workflow.

What is the physical size and mounting method of the TEMLP001?

The TEMLP001 measures 2.3 × 1 × 0.6 inches (58.4 × 25.4 × 15.2 mm) and has no mounting holes or standoffs. It is intended for benchtop or fixture-integrated use via its exposed SMT pads. No PCB footprint or mechanical mounting provisions are defined-integration relies on custom cable routing and external mechanical retention in test jigs or lab setups.
